Clinical Question:
Does doxycycline work better than placebo in resolving symptoms of sinusitis in adults?

Bottom Line:
The addition of doxycycline adds no important benefit over the use of topical nasal decongestants. This is consistent with recent recommendations from the CDC that no antibiotics be used in the treatment of acute sinusitis unless the patient is symptomatic for over 14 days or if the infection is severe.

Study Design:
Randomized controlled trial (double−blinded)

Synopsis:
Acute sinusitis-like complaints are very common and are usually treated with antibiotics in spite of the lack of evidence for the effectiveness of antibiotic therapy and the increasing number of resistant strains. The authors  assessed the effectiveness of doxycycline in adults with acute sinusitis-like complaints in general practice. The effects of doxycycline in a placebo-controlled, double-blind, randomized trial were assessed in adults consulting their general practitioner (GP) with complaints after a common cold or influenza, pain in the head when bending forward, purulent nasal discharge, predominantly unilateral maxillary pain, toothache, or pain when chewing. Primary outcome events were the resolution of facial pain and the resumption of daily activities. Treatment differences were assessed by means of Kaplan-Meier curves and hazard ratios. The follow-up period was 42 days. No significant difference was found in time to recover between the doxycycline-treated group and the placebo-treated group. However, the adjusted hazard ratio for the group receiving doxycycline was 1.17 (95% CI = 0.87-1.57) for the resolution of pain and 1.31 (95% CI = 0.96-1.78) for the resumption of daily activities. After 10 days, 85% of all patients reported improvement and 60% were completely cured. Side effects were reported by 17% of the doxycycline-treated group, with two patients withdrawing because of side effects..
